Relationships between obsessive-compulsive symptoms and several cognitive constructs that are theoretically
related to such symptoms were investigated among university students. A total of 211 subjects filled in a measure of
the frequency of intrusive thoughts based on Clark and de Silva (1985), Salkovskis' Responsibility Attitudes Scale
(RAS) (Salkovskis et al., 2000), the Thought-Action Fusion Scale (TAF) (Shafran, Thordarson, & Rachman, 1996),
Wegner and Zanakos' (1994) White Bear Suppression Inventory (WBSI), and the Maudsley Obsessive-Compulsive
Inventory (MOCI) (Hodgson & Rachman, 1977). The main hypothesis addressed was that in accordance with
Salkovskis' model (1996) responsibility and thought suppression serve as mediators between intrusive thoughts and
obsessive-compulsive symptoms as measured with the MOCI. The results were consistent with the model.
